1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and procurement specialists, the core challenges in primary crushing often center on three critical areas:

Unscheduled Downtime: Frequent mechanical failures and wear part changes can halt your entire processing line. Industry data indicates that for a midsized quarry, every hour of crusher downtime can result in over $1,200 in lost production and labor costs.
Rising Operational Expenditure: Are you constantly budgeting for premature component replacement and high energy consumption? Inefficient crushing chambers and drives directly increase cost per ton.
Inconsistent Output & Quality: Fluctuations in feed size or hardness leading to poor product gradation, slabby material, and excessive recirculation load creates bottlenecks downstream.

The central question becomes: how do you specify a primary rock crusher that delivers not just raw power, but predictable performance, lower total cost of ownership, and sustained product quality?

2. PRODUCT OVERVIEW

The Nordberg C150 Jaw Crusher is a heavyduty, singletoggle primary crusher engineered for the most demanding mining and quarry applications. It is designed as a longterm asset for stationary crushing plants where high capacity and reliability are nonnegotiable.

Operational Workflow:
1. Feed Intake: Large runofmine material (up to 40”/1016 mm) is delivered to the vibrating grizzly feeder.
2. Primary Reduction: Material enters the deep, nonchoking crushing chamber where a robust eccentric shaft drives the moving jaw in an elliptical motion.
3. Discharge & Clearance: Crushed material exits at the bottom with a consistent discharge opening setting, minimizing risk of chamber clogging.
4. Downstream Transport: Sized product is conveyed to secondary crushing or screening stages.

Application Scope: Ideal for hard rock mining (granite, basalt), largescale aggregate quarries, and industrial mineral processing. Its design is optimized for highcapacity stationary plants with consistent, large feed material.

Limitations: Not suitable for mobile crushing circuits, recycling applications with high rebar content, or processing highly abrasive sand without specific liner alloy options.

3. CORE FEATURES

Fixed Jaw Die Retention System | Technical Basis: Bolted wedge assembly with zeropoint lifting tools | Operational Benefit: Enables safe, fast jaw die changes by maintenance crews; reduces liner changeout time by up to 50% compared to traditional welded designs. | ROI Impact: Direct labor cost savings and increased plant availability translate to higher annual throughput.

STELLAR™ Raw Frame Design | Technical Basis: Finite Element Analysis (FEA)optimized cast steel construction with integrated lifting points. | Operational Benefit: Provides exceptional durability against fatigue stresses and shock loads from uncrushable objects; simplifies installation and relocation. | ROI Impact: Extends structural life beyond the industry average, protecting your capital investment against frame cracking.

Large Diameter Eccentric Shaft | Technical Basis: Forged from highintegrity alloy steel, mounted in spherical roller bearings. | Operational Benefit: Delivers high inertia and smooth operation under peak loading conditions; bearing design accommodates misalignment and reduces friction losses. | ROI Impact: Improved energy efficiency (field data shows 58% reduction vs. older designs) and extended bearing service intervals lower operating costs.

Safe Adjustment System | Technical Basis: Hydraulic setting adjustment via pushbutton controls with mechanical shim backup. | Operational Benefit: Allows operators to adjust the crusher discharge setting quickly and safely from outside the crusher; facilitates compensation for wear without stopping the feed. | ROI Impact: Maintains target product specification consistently, reducing offspec material and maximizing saleable yield.

Integrated Motor Base & Drive Guards | Technical Basis: Unified fabrication incorporating Vbelt drive guards and motor mounting points. | Operational Benefit: Simplifies installation alignment, reduces footprint clutter, and provides superior safety compliance for rotating parts. | ROI Impact: Reduces installation time/costs by approximately 30% and mitigates risk of safetyrelated stoppages.
